The following table reflects the results of a hypothetical studyinvestigating the effects of cognitive strategy on dealing with physical or emotional pain. Participants were randomly assigned to one of two cognitive strategy conditions, distraction or reframing. Half of the participants in each condition were then exposed to physical or emotionally painful stimuli and instructed to use the cognitive strategy while being exposed to the stimuli. The researchers measured the participants’ heart rates as an indicator of the amount of stress experienced.Table: Coping with Pain   Distraction Reframing Mean Emotional Pain 93.4 84.4 88.9 Physical Pain 136.8 85.6 111.2 Mean 115.1 85.0     Reference: Ref 14-2 (Table: Coping with Pain) Based on the cells of this study, which effects appear to be present?

To investigate serotonin’s role in suicidal behavior, the amounts of serotonin metabolites in the cerebral spinal fluid of 18 violent-suicide attempters are compared to the levels found in a group of 24 nonviolent-suicide attempters. The levels of serotonin metabolites are coded as low or normal/high, and the two groups are compared. These data would most appropriately be analyzed with a(n):

For the data in the source table, what decision can be made about the hypotheses being tested? Source SS df MS F Between-groups 15.16 3 5.053   Subjects 7.67 5 1.534   Error 21.42 15 1.428   Total 44.25 23    

The issue of order effects in a within-groups ANOVA can be resolved by using:

(Table: Light Therapy) Sit and colleagues (2018) investigated the efficacy of adjunctive bright-light therapy in patients with bipolar disorder. Patients were randomly assigned to receive either bright-light therapy or dim-light therapy along with their regular medication. After six weeks, patients’ clinical status was coded as improved or not improved. (a) Calculate the chi-square statistic for a test of independence to determine the effects of the type of light therapy on the patients’ clinical outcomes, and interpret what this result means. (b) Calculate the effect size for this test, though you don’t have to interpret the effect. The data appear in the table.Table: Light Therapy   Improved Not Improved Bright Light 15 8 Dim Light 4 19  

According to guidelines published by Cohen (1988), a correlation value of 0.34 would be considered:

Homoscedasticity can be tested for by:
